(Cl. lit-128) 3 claims. l

My invention relates to -a new and improved hollow and bendable and resilient shoe-form, which is used as a mount for shoes in display windows and the like.

According to my invention, I make said shoei'orm of two separately molded one-piece bodymembers, which can be made of any suitable resilient plastic of the thermoplastic or thermosetting type, or of any other moldable material. These one-piece body-members are respectively designated as a pin body-member and a socket body-member.

Each said one-piece body-member can be made by injection molding or in any other manner. Said body-members are preferably made of the same material, such as cellulose acetate. Each said body-member has an internal concave or recessed face, so that each said body-member has a rear upstanding flange, a top ange, and a bot- .tom flange. The rear upstanding ange may have an external concave face. The top end of said upstanding flange is continuous with a rear portion of the top flange. Said rear portion of the top flange may be planar and horizontal. At

its front end, said rear portion of the top flange is continuous with a downwardly inclined front portion of said top flange, which extends to the front of the form.

The bottom flanges of the assembled bodymembers are shaped so that their edges are spaced from each other, save at the heel and toe of the form, at which the edges of said bottom flanges abut to form a suitable joint, as exempliiled by a lap-joint. The edges of said rear and top flanges also abut each other to form a suitable joint, as exemplified by a lap-joint.

. Each said body-member can be molded, as by injection molding, from the same thermoplastic material, as exemplified by cellulose acetate.

It is well-known to bond bodies made of thermo-plastic material to each other by using a suitable cement, or by softening the edge-portions of said bodies and pressing said softened edge-portions against each other. Such bonding methods are described at pp. 608-609, 615 of Handbook of Plastics by Simonds and Ellis, published in 1943 by D. Van Nostrand Company Inc.

It is very difficult, if not possible, to hold two such resilient body-members in proper assembled relation by means of a lap-joint while bonding them, or to provide a secure union between such resilient body-members by merely bonding them at the edges thereof which form the joint. According to my invention, I provide the pin body-member with a plurality of integral and imperforate pin-lugs, each of which has a planar end-face from which an integral reduced assembly pin extends laterally beyond the edges of the flanges of said pin-body member. Said planar end-faces of said pin-lugs are flush with the inner lip which forms the inner element of the lap-joint. I provide the socket body-member with a plurality of integral socket-lugs, which have respective recesses in which the respective assembly pins iit accurately when said bodymembers are assembled. Said socket-lugs have planar end-faces, which abut the planar endfaces of the pin-lugs, when said body-members are assembled. When thus assembled, the endfaces of said assembly pins are spaced laterally from the inner end-wall of the recesses of said socket-lugs. This combination ensures an easy and accurate assembly of the body-members. Said assembled body-members are bonded to each other, either by using a cement or a softening agent, at the elements of the lap-joint. Optionally, said body-members may be thus bonded to each other at the abutting faces of the pin-lugs and socket-lugs, and also optionally at the assembly-pins and the internal walls of the recesses of the socket-lugs.

Other objects and advantages of my invention are stated in the annexed description and drawings Which illustrate a preferred embodiment thereof.

Fig. 1 is a side elevation of the assembled form;

Fig. 2 is a bottom plan view of the assembled form, partially in horizontal cross-section;

Fig. 3 is an internal elevation on the line 3-3 of Fig. 2, showing the pin body-member;

Fig. 4 is a section of the assembled body-members, taken along the line 4 4 of Fig. 3; and

Fig. 5 is a section of the assembled body-members taken along the line 5-5 of Fig. 3.

The drawings are substantially to scale of a commercial embodiment, and reference is made to such scale as part of the disclosure to disclose the shapes and relative sizes of the parts.

The pin body-member 2 has a lip 8, which forms the inner element of the preferred lapjoint, as illustrated in Fig. 5. This lip 8 is interrupted between the horizontally disposed points 6 and 1, which define the ends of the bottom flange of pin body-member 2.

Directly adjacent to and directly inwardly of lip 8, the pin body-member 2 has a plurality of integral pin-lugs 3, each of which has a planar end-face, as shown in Fig. Z. Each pin-lug 3 has
